How this service works
Did my agent overpay for x402 APIs? The wallet overspend audit reads a buyer wallet's USDC payments on Base and checks each against the payee's listed Bazaar price: payments above the listed price, oversize settlements of 10x or more, and payments to addresses with no listing, totalled per seller. Use when an agent or its operator needs a spend audit of an x402 buyer wallet.
Output
Returns a summary object with total payment count, total USD spent, total USD overpaid, and count of oversize payments (10x or more), plus a plain-English headline. Also includes a receipt with a receipt ID and impact pledge details.
Example use cases
Agent operator weekly overspend review
“Audit my x402 buyer wallet 0xDef456... for the past 7 days — I want to see if my agent paid above the listed Bazaar price for any APIs, and flag anything that was 10x or more overpriced.”
Detecting payments to unlisted sellers
“Check my wallet 0xGhi789... over the last 30 days for any x402 payments that went to addresses with no Bazaar listing — I want to know if my agent sent money somewhere it shouldn't have.”
Monthly x402 budget reconciliation
“Pull a full 30-day overspend audit for my x402 buyer wallet 0xJkl012... so I can reconcile how much more my agent paid versus what those APIs were supposed to cost on Bazaar.”
Technical details
Endpoint
GEThttps://api.agoranome.com/v1/buyer/audit?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent operator or the agent itself needs a structured financial audit of x402 API spending on Base — specifically to detect overpayments relative to Bazaar listed prices, catch oversize settlements, and identify payments to unlisted addresses. Prefer this over general blockchain explorers when you need x402-specific price comparison logic already built in.
Side effects
- Invalid or malformed wallet address returns an error
- Days parameter outside 1–30 range is rejected
- Wallet with no payment history returns empty/zero summary
- Bazaar price data unavailable for some payees may result in incomplete audit
- Network or blockchain RPC timeouts may cause partial results
